Problems solved by technology

The I-shaped straight thrust rod can only transmit the longitudinal force such as the driving force and braking force between the frame and the axle, but cannot bear the lateral force and has no anti-rolling ability. It must be equipped with a lateral stabilizer bar, but its anti-rolling ability still poor

Embodiment Construction

[0038] Such as Figure 1~4 As shown, the X-arm 1 for the vehicle air suspension of the present invention includes a body 11, and the body 11 is integrally formed with:

[0039] A pair of axle connecting arms 12 extending outward from the body 11 and arranged symmetrically, the end of the axle connecting arm 12 away from the body 11 is the axle connecting end; the axle connecting end has a mounting hole for connecting with the axle ;

[0040]A pair of beam connecting arms 13 extending outward from the body 11 and arranged symmetrically, the end of the beam connecting arm 13 away from the body 11 is a beam connecting end; the beam connecting end has a mounting hole for connecting with the beam;

[0041] The axis of symmetry of the axle connecting arm 12 coincides with the axis of symmetry of the crossbeam connecting arm 13, and the two axle connecting arms 12 and the two crossbeam connecting arms 13 are arranged opposite to each other on the axis of symmetry to form an X or H s...

Abstract

The invention relates to an X-shaped arm for a vehicle air suspension, and further relates to an air suspension assembly adopting the X-shaped arm. The X-shaped arm for a vehicle air suspension is characterized by comprising a body; a pair of axle connecting arms which extend outwards from the body and are symmetrically arranged and a pair of cross beam connecting arms which extend outwards from the body and are symmetrically arranged are integrally formed on the body, and the two axle connecting arms and the two cross beam connecting arms are arranged back to back on the symmetry axis to forman X shape or an H shape; and in the outward extending direction of the body, the cross sections of the cross beam connecting arm and the axle connecting arm are gradually reduced. The X-shaped arm has the advantages that the stress effect is good, and the structure is stable; and after the molded lines and the cross sections of the axle connecting arm and the cross beam connecting arm are optimally designed, the structural strength and the stability can be greatly improved, and weight reduction optimization can be carried out on the premise.

Description

[0001] The present invention was submitted on August 1, 2019, the application number is 201910706995.6 (parent application), and the invention name is "an X-arm for vehicle air suspension and an air suspension assembly based on the X-arm" A divisional application of a patent application. technical field [0002] The invention relates to an X-shaped arm for vehicle air suspension, and also relates to an air suspension assembly based on the X-shaped arm. Background technique [0003] In the context of energy saving and environmental protection, lightweighting of automobile chassis and energy saving and emission reduction are the main development directions of various manufacturers. As an important part of the chassis system of heavy-duty trucks, thrust rods also need to be lightweight. [0004] At present, the rear suspension systems of mainstream heavy trucks mainly include air suspension systems and balanced suspension systems, both of which are matched with thrust rods, and...
